Again, thanks for the tips...
I eventually worked out the problem. And its pretty embarrasing
When working on the bike i had plugged up the bottom of the airboot to stop dust and what not geting in. I'd actually forgotten to remove this and it had just been sat there chokeing off the air supply...
Removed the kitchen towl, problem solved...
ALTHOUGH! The idle and pilot screw tips really helped with the set up.
Thanks again guys
